SPECFICAIIDN forming part of'Letters Patent No. 283,436, dated August 21, 1883, Application filed December 4, i882. (Model.)

To .all whom t iii/ay concern Be it known that we, FREDERICK B. 'finironnn and Josnrn W. Jonsson, both of New Brit ain, in the county of Hartford and State of Confi is a view of same in central cross-section on plane :c :c of Fig. 3. Fig. 5 is a view of our device in position as when the bottle is filling. Fig. 6 qis a similar view, th'e neck of thebottle being shown in section, showing the rubber in the position it assumes when the liquid is passing into the bottle. Fig. 7 is a side view of the perforated cap-plate or cover. Fig. Sis a plan view of the neck-band and cam-lever, and Fig.

9 is a side view of the cam-lever.

This invention relates to that class ofbottle' Stoppers and .fasteners which employ, essentiaily, ametal cap-plate having a rubber plug or stopple or packing with a valve, a neck-band,

` and fastening means for holding the stopper part in the mouth of the bottle; and it has for its main object to remove defects in the devices that have heretofore been used or suggested,

and to make a better, if nota perfect, seal for a bottle contaiiuing` s oda or carbonated liquid. 1With these and other objects in view our improvements consist in the special construction and form of the elastic plug or stopple In the accompanying drawings, the letter ci denotes a bottle of ordinary form and material,

having secured about its neck ametallic band,

Z), to which is pivoted on one sidealink, c, usuy ally of wire, and dianietrcally opposite to this is pivoted .a cam-lever, d.

To the link o is pivoted the metallic cover e,

which has a centra-'i downward-proj ecting stem,

e', with a' central perforation, e2. The yoke or link f is pivot-ed to this cover in such position as to enable its lower loop to engage the hook d of thelever when its handle is turned upward.

The elastic plug or stopple g is made, preferably, of india-rubber, and it has a central mortise, g, contracted in its upper part to form the' shoulder h, and'adapted to fit closely upon and conform to the stem e! of the cover. This plug is raised near the center of its top (which is dat, with chamfered edge, as shown, or hemispherical) above the plane of the upper edge of the rim, which edge is undercut or formed to fit the contour of the mouth of the bottle, forming flange g2. About midway of the body of the plug g its lateral walls are perforated by l one or more (in the form shown by four) vents, 7J, and through these and the stem the bottle is filled on the ordinary bOt-tleiller.

Ilhe various parts of our device, when the bottle is lling, are arranged about as shown' in Figs. 5 and 6, the inwardly-turned point of the cam-hook d holding the yoke, the liquid and gas forcing the flat bottom of the plug aw'ay from the bottom rim of the stem, and passing up to and through the lateral vents into the bottle. As soon as the filling is completed the lever is forced down against the bottle and locked there by the upward pull of theyoke, as seen in Fig. l. The elastic plug is forced into the mouth of the bottle as the lever is thus depressed, the pressure coming iirst upon the upperpart of the plug near its center, and this crowds the material'into the mouth, packing it firmly into the space between the bottle and the stem of the cap. As the cap isfurther depressed in looking, it compresses the flange g2 between the cap and the bottle, and also draws the fiat bottom of the plug tightly against the.

lower rim of the stem, forming a perfect stopper against gas and liquid. The pressureof the gas in the closed bottle tends to shut the passage through the vents and under the rim even more closely. The complete closing ofthe bottom of the plug and the lateral location of the vents, in combination with the central packing feature of the plug, form the main features of our invention.

2. The combination7 substantially as hereinbefore described, of the cap-plate having an 15 elastic plug connected thereto7 With the neckband7 the connecting-link pivoted to both neckband and cap-plate, the yoke or lin'k f,fpivot ally connected to the cap-plate7 and the camlever d, pivotally attached to the neck-band'for 2o engaging With said yoke or link f, as set forth.
